This paper describes the technical and aesthetic challenges faced in the recent software-based recreation of composer Dexter Morrill’s work Sea Songs for soprano voice, computer-generated tape and Radio-Baton controlled hardware effects-processor. Through careful analysis of the composer’s own notes as well as through extensive testing of Morrill’s original Digitech TSR-24 stereo-effects processor, a flexible and extensible software emulation of the piece was created as a Max/MSP application.
